How can I create my HUD? Is there anyway to make an animated HUD?
Hello!
Look into FPS example (blueprint) and find a blueprint called: myHud. You should find some basic examples there 
when it comes to animation, I would probably just update the picture frame by frame.
Click on Blueprints on the top bar in your editor and you will see the option to create a new HUD.
You must also tell the game to use the HUD you created. For that, you need to go into the GameMode and select your HUD as the HUD class there. You can have several different HUDs for your different GameModes in your levels (e.g. Title HUD for New Game, Load Game etc. and an in game HUD for inventory, weapons etc.).
